与it有关的主要句型
it强调句型
知识总结归纳:
(一)it用做形式主语或形式宾语:根据句子结构的需要,it用做形式主语或形式宾语,而真正的主语或宾语(to do 短语,doing短语,名词性从句)则放在句尾。
主要句型:
It’s +形容词/名词+连词+名词性从句
to do sth.
doing sth.
find / make / think / feel it +形容词/名词+连词+名词性从句
to do sth.
doing sth.
例句:

4. It was once predicted(预测)that British and American English would become separate languages finally .
(三)it在强调句型中:在英语中,为了突出强调句子的某一个成分(谓语除外),达到强调或使听话人特别注意这一部分的目的。便形成了一种强调句型。
It is / was+被强调的部分+that / who+句子的其他部分。
It is / was not until+时间+that+句子的其他部分。
例句:
1. I saw John on my way to school this morning.
It was John who/that I saw on my way to school this morning.

2. Where was it that you met the foreign guests from Australia?
3. I can’t quite remember when it was that we married.

3. It was almost ten o’clock when our soldiers came back from the front.
